Last updated: April 2026 --- ## General **What is AutoSend?** AutoSend is an email platform for sending transactional and marketing emails. It is built on Amazon SES infrastructure. Pricing is volume-based (per email sent), not per contact stored. **Who is AutoSend for?** Startups, SaaS companies, indie hackers, and developers who need transactional or marketing email. Non-technical users (founders, marketers) can use the dashboard for marketing emails and campaigns without writing code. Developers use the API or SMTP for transactional email. **How fast is email delivery?** Transactional emails are delivered within seconds. Optimized for time-sensitive messages like OTPs, password resets, and order confirmations. **What can I do without a developer?** Send marketing campaigns, manage contact lists, view analytics, configure deliverability settings, and set up automations. All available through the dashboard. **What requires a developer?** Integrating transactional email via the API or SMTP. SDK setup, webhook configuration, and programmatic contact management. **What if I don't have technical knowledge but need to integrate AutoSend?** Install the AutoSend MCP server or the AutoSend skill (skill.md) in your AI agent. The agent can handle API integration, contact management, campaign setup, and sending on your behalf without you writing any code. --- ## Pricing and Billing **How does pricing work?** Volume-based. You pay for the number of emails sent, not the number of contacts stored. **Is there a free plan?** No. The Hobby plan starts at $1/month with no daily sending limit. The minimum fee prevents abuse on shared IPs and keeps deliverability reliable for all customers. **What happens if I exceed my plan's email limit?** You can upgrade instantly or pay for additional usage at a flat per-email rate based on your plan tier. AutoSend notifies you at 90% of your quota and never blocks emails mid-campaign. You can send up to 1x additional emails on top of your monthly sending limit. **Can I change plans anytime?** Yes. Upgrade, downgrade, or cancel at any time with no penalties. **Billing cycle?** Monthly only. Billing recurs from your subscription start date. **Refunds?** Refunds are available only if there is no usage and requested within 7 days of subscription start. Hobby plans are not eligible for refunds. **Custom or enterprise pricing?** Available for customers sending over 1.5M emails per month. Includes dedicated infrastructure. **How do I choose a plan?** Hobby for side projects. Starter for builders and small startups. Growth and Scale for companies that need better per-email pricing at higher volumes. Enterprise for 1.5M+ emails/month. **Hidden fees?** None. The only optional add-on is a dedicated IP for high-volume senders. --- ## API and Integrations **API type?** REST API. Documentation at docs.autosend.com/api-reference. **SDKs?** Node.js SDK available, which includes a Resend adapter for easier migration. **SMTP?** Yes.
